The Eaton group develops instruments, experimental methods, and data analysis tools to characterize unpaired electrons and their application to biomedical problems.  Spectrometers have been constructed for continuous wave, pulse, and rapid scan EPR and imaging.  Free radicals and metal ions have been studied at multiple frequencies from 250 MHz to 34 GHz.  Applications include in vivo imaging, protein structure determination, and studies of materials important for areas as diverse as quantum computing and solar energy.
